Execution Time	60.04962ms
Answer	TIMEOUT
Input	Zantema 04 z104

stdout:

TIMEOUT

We consider the following Problem:

  Strict Trs:
    {  a(c(c(c(x1)))) -> d(d(x1))
     , b(d(x1)) -> c(c(x1))
     , d(x1) -> b(b(b(b(x1))))
     , c(x1) -> a(a(a(a(x1))))
     , d(b(x1)) -> c(c(x1))
     , c(c(c(a(x1)))) -> d(d(x1))}
  StartTerms: all
  Strategy: none

Certificate: TIMEOUT

Proof:
  Computation stopped due to timeout after 60.0 seconds.

Arrrr..
